.AG-ITATOR.

Application filed september 5, 1922. lserial No..5`se,234.

To all whom 'it may concern:

Be it known that I, EDWIN S. LEINAN, a citizen of the United States,residing at Fargo, in the county of Cass and State of North Dakota, haveinvented certain new and useful Improvements in Agitators, of which thefollowing is a specification.

This invention relates to an improved agitator for culinary use Vin thebeating of eggs, whipping of cream, and like operations.

rlhe primary object of the invention is the provision of an agitatorwhich includes relatively few parts, which are compactly astivelyperform the use for which the same is provided.

An important object of this invention is the provision of an agitatorincluding a knumber of dashers which includes a driving mechanism ofadjustable character to compensate for wear upon the different partsthereof.

A further and important object of this invention is the provision of animproved agitator including a plurality of novelly arranged dashermembers. A

Other `objectsand advantages of the improved agitator will be' apparentduring the ycourse of the following detailed description.

proved agitator, showing several' parts thereof in section, in order todisclose the cooperative relation of the agitatorpdetails. Figure 3 is afragmentary view, partly in section, showing cooperating parts of thisinvention. Y.

Figure 4 is a fragmentary cross sectional view, showing an adjustableView of 'the agitator operating mechanism.

In the drawing, wherein for the purpose of `illustration is shownthepreferred embodiment of this invention, the'letter A ge .n'ericallyindicates the improved agitator,

includingv a SuppOrtB; outer dasher arrangement C intermediate y'dasherarrangement D; inner dasher arrangement E and operating means F.

`nisn'rF to b'e subsequently mentioned. The

The support B preferably includes avflat 'Y metallic plate 10 vprovidedwith a recessy 11 eirten'dlng upwardly from the -lowerfmarginal'edgethereof and being provided with a transverse opening 12 adjacenttheoppo-z r site end thereof, said depression llitand opemng 12`beingrespectively provided `for accommodation of certain elements of thedasher arrangements C and D, whichwill be more specifically mentionedhereinafter.

The upper end of the supporting plated() is preferably provided with alooped handle"y y portion 14. sembled in adjustable relation to mosteffec- Referring, to vtheu'dasher arrangement C, the same includes ab'evelledpinion .'15 having a sleeve portion 16 formedupon one sidethereof which :is circumferentially grooved for receiving a retainingcollar-18,

which is clamped as by'rivets 19 to thesupi f porting plate 10. In'thisrelation, the, pinion is mounted in the recess 1l-of vthe 'plate '10,.bearing within the collar v18, 'and cooperating with certain parts oftheguide mechaarrangement C furthermore includes thel dasher member 21which is formed of wire or analogous material having certainspaced arms22 which are connectedv` at their ends to thepinion 15, and depend inspaced parj allel relation-to support the loop23 of rigid" formation. jI

The intermediate dasher D includes a pinion 25, which isl provided witha. portionj26 extending outwardly therefrom grooved for receiving abearing colla'r 27, said bearing'` collar 27 being secured, asbyrivetsz2`8 to the same side of theyplate 10 asth'e :collar 18A isVconnected to, andas is illustratedin Figures 1 'and 2 ofthe drawings.Ashaft BO extends axiallyfr'om. the portion 26 ofpin l ion 25, anddepends throughtheaX-ial passageway Oafformed through the pinion 15;

saidshaft 30 being provided with the passageway v31 openingv from the`lower end thereof. The shaft 30 thus vextends between the arms 22 of thedasher member-121, and is provided with va ring shaped dasher 'end 32upon thelower end'thereof which-is rela'- tively smaller in diameterthanthe outer dasher ring v23,- so Ythat thefring 32 is'in fact, confinedwithin the vrarea -of theJ loop 23. r.

It is to be noted, that the collar` retains the pinion 25 withintheupperl opening 12.

The inner dasher is lof novel formation, and includes the plateportion'` 35 having certain apertures 36 therein to permit free passageof the liquid in which the agitator A is operated. The plate 35 isprovided with a stem 37 extending outwardly from one end thereof bearingwithin an aperture 39 in the lower end of the dasher loop 32 and beingaffixed as by welding at 40 to the lower end of the outer baffle loop orring 23. The plate 35 is also provided with `a stemp4l which extendsopposite to, and aligns with respect to the stem 37, said stem 41 havingan enlarged ybearing end 42 thereon, which is journalled within thepassageway 3l of the shaft 30, so that the plate 35 is disposed withinthe area of the intermediate dasher loop 32, as is illustrated in Figure2 of the drawings.

Referring now to the operating means F, the same includes a stub shaft45, which extends from the surface 46 of the supporting plate 10, said`stub shaft 45 being screw threaded at 47 upon its free end foradjustably receiving athumb nut 43. A master bevelled gear 50 isprovided having a polygonal shaped extension 5l axially at one sidethereof, said gear 50 having an opening axially thereof for receivingthe stub shaft 45, in order that the same may bear thereon. A crank 52may be provided over the polygonal portion 51 of the master gear 50 inorder to rotate the same upon the shaft 45. As is illustrated in 'Figure2 of the drawings, the master gear 50 is so disposed upon the shaft 45that the teeth there of are 1n engagement at opposite points with thepinions l5 and 25. The nut 43 may be so adjustedupon the screw threadedportion 47 of shaft 45 that the master gear 50 may be adjustedlongitudinally of the shaft 45 for engaging the teeth of said pinions.

In operation, it is apparent that as the operator rotates the mastergear 50, the pinions l5 and 25 will be turned in opposite directions forrotation of the dasher loops 23 and 32 in opposite directions. Due tothe fact that the inner dash member E is fiXedly connected to the loop23 and bears within the intermediate dasherl arrangement D, it isobvoius that the oval shaped plate 35 will be rotated in the samedirection as the outer dasher loop 23. This is a superior arrangement,since thereby an egg, or cream may be beaten in a relatively shortertime, and 1n a more effective manner than can be done with present typesof agitators. It is well known, that agitators embodying the piniondrive arrangement soon become inoperative,

due to the wear upon the pinions and drive Y gear, as to cause slip ofthe teeth thereof.

This invention provides for such wear and for any loose bearings, bymaking the master gear 50 longitudinally slidable and adjustable uponits bearing shaft 45, so that the same may properly engage the pinionsl5 and 25 1n operating relation.

From the foregoing, it can be seen that an agitator has been providedwhich while simple in operation is very durably oonstructed, embodyingimproved beating facilities, and improved adjustable assembly tocompensate for wear upon the parts incident to operation.

Various changes in the shape, size and arrangement of parts may be madeto the form of agitator herein shown and described without departingfrom the spirit of this invention or the scopev of the claims.
